Re: STDIN behaves different according to context

When I'm trying to use <STDIN> in scalar context my scripts are executed without me being able to give an input

It sounds like something is already waiting on STDIN when you read from it. So when you read from STDIN in a scalar context it will read whatever's waiting but in list context it will continue reading until it receives an EOF. Further information about your system and perl version would go a great way towards finding a solution.

In such a case, it might be useful to figure out what exactly is coming into STDIN without your knowing about it. Try converting each character to its numeric value and write that: `my $a = <>; local $, = ' '; # Put some whitesapce between each number print unpack("U*", $a), "\n";` [download] Above is untested, as always. ---- Invent a rounder wheel.

Also, it would be useful to know how the script is being called. If you're running it by calling (dumb example): `$ echo '' \| myscript.pl` [download] then I can see the problem. LAI :eof	[reply] [d/l]

I figured out what is waiting in STDIN, it is a "new line feed or a new line", the numeric value 10. What system and version am I using? I'm using the perl version 5.6.1 for MSWin32-x86-multi-thread. I'm runing my programs with CYGWIN, a Unix environment for Windows.	[reply]
